I agree.  The circumstances on the systems are different and I suspect that
the root causes may be different.  It's possible Hezekiah's problem is
related to the multiple installs of plplot lying around; certainly the ldd
results are a little odd.  That's not to say that there isn't/wasn't a
memory corruption/overwrite/misuse issue occurring as well.

Correct, and as such they can be cows to track down.  Adding debug code for
example an appear to make the problem disappear.
